Since it is impossible to increase LB2 damage for dev (they unlikely to revert what they did previously, when DH was released initially LB 2 can 1 shot glass canon) I would reckon to increase the area of LB2 or decrease CD or remove root. LB5 is a bit suicidal in PvP unless they reduce casting time (like LB 5 for ranger) / remove root. LB 3 if possible, make it travel slower so it has higher chance to block more projectile. Of course, if they can make knockback as base it would be awesome but since dev has no intention to do so since this has been asked for many years and no change has been seen.
